To all whom it may concern:

Be' it known that 1, THOMAS. HILL, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Hose- Clalnp, of which the following Vis afull, clear, and exact descriptio This invention relates to clamps and has particular reference to hose clamps or analogous devices. l

Among the objects ofthe invention is to provide a clamp including anchorage means and a flexible band adapted to be secured at 'remote portions oi the anchorage means for deslred'purpose. u A more definite' object of the invention is to, provide a clamping devlce for a hose or the purpose ot' contracting the band for any other, purposes including -an anchor devicel comprising a cradle havinga rounded, concave bearing and a rocker coperating with the bearing whereby the direction of Strain applied to the band, or its equivalent, will always accommodate itself. automatically to the most advantageous condition irrespec tive of the size or diameter of the hose or other device encircled by the clamping band.

With the foregoing and other objects in view the invention consists in thc arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the samev parts in the several views, and in Which- Figure 1 is a cross section of a joint of hose showing one form of my improvement applied thcrearound.

Fig. 2 is a vertical transverse section of the same.

3 is a plan vien1 of the same, the free end portion of the ban/l being4 in section.

Fig. f1 is adetail perspective view of the cradle portion of the anchorage means.

Fig, 5 is a similar view of the rocker.

Fig. 6 is a transverse sectional view show ing the same mechanism adapted to a rod or part of minute diameter.

Fig. 7 is a rear elevation of the same parts uas in Fig. 6. i Fig. 8 is a modified form and adaptation ,of approximately as employed for prlsing a cradle member 18 shown in detail in F ig. 4. and comprising two side wings 19 occupying substantially parallel planes and triangular form. These wings are connected by a concave wall 20 and a crossbar 2l. This cradle member may e made in any suitable manner or of any approved material, but I find that it may be made cheaply and conveniently from sheet metal suitably stamped into shape. The

`wing members 19 are provided with concave ter of the edge alined bearino` seats 22 and the concave wall 20 is preferab y notched at 23 along the cennearest to the crossbar 21 and substantially midway between the ends of the wings. The anchorage device includes also a rocker 24 having a convex bearing surface 25 adapted as shown in Figs. 1 to 3 as bearing in the bearing seats 22 at the ends of the wings while the screw'bolt 15 projects through a central hole 26 vhose axis is perpendicular tothe axis of the rocker 24 as a whole. Ii desired the ends of the rocker may be provided with parallel lips 27 adapted to engage over the outer faces of the wings 19 and so prevent any possibility 0f endwise displacement of the rocker in practice, The surface of the rocker opposite the rounded hearing surface 25 may be of any suitable shape, but if the device is stamped from sheet metal the form will probably be preferably of the form .shown in Fig. 5y in which there is a concavity 28 formed therein. The head of the screw bolt bears against this face 'of the Vrocker in the adaptat1on shown in Figs. l to 7.

The compression member29vmay be of any suitable nature such as a narrow strip of thin `sheet brass or other strip material which may be found of a suitable width or which may be cut to suitable width. As indicated in Figs. 2 and' this compression plan view of the upper portion or oiher perl being clamped who ,is .all held by friction heijveen 'the l' :onlin portion of sille'conipress me "l" remote pon @tion of the compression member is then connected to tension member l5 by passing die screw through one of the holes 30 el:

epproxinmteiy :i righi length for the percicner job, but with "the nut i7 relatively loose end applied on the iree end of the screw on the ouside of the compression niembeig the shouldenuortion of the screw being.; jonrneled in 'the .iole' of the rocker and 'with the iipe 27 direcied toward the nui. The workmen then passes ille compression meinbereround the hose or the like, and holding cradle with the concave veily 20 'thereof against the hose, he will then bring the tension member end rocker portions around the hose and sei? rlie roclrer in the bearing seais 22. The paris will be then self-susi;siningl and he will apply force to ilbe tension n'ieniber by use ofn screw driver applied io lille head lo. The drain exerted ley lie tightening); of the iension member will 'meiic eiinement of ille tenscrew io ehe direction of the The nut will hiie into e releively sharp ongle ci 'lie compression member be tween he screw and the hose and so Will'be held :from rotn'ion. The rocker will automatically roll or adjust itself in he boerin 22 accerdnig lio the dismessi of the hose or peri encompassed by the compression member. 'llfhcn the rocher is once npplied to the le iii is impossible for it to slip out oi* nl From the nature of the connection beiween the compression member and the cross ber 2 iihe approximate length Doi the compression member may be readily deiern'iined inannnuch es the. inturned free end oi the congilression member lying between the hose und the main portion may be of :my variable length. There is no possi bility for the tension member 15 to crmnp `or bind during; the iii telling' or loosening action due io the peculiar copereizion between iilie nui :md bhe free end ofihe cornpression member und nature of Jche rocker acting the bearings of the cradle. Conseinienly wiih the Lessig amount o1 3d danger o'iE stripping the threads on neviher 'the nms'inium coini cred.

on of the eieren n :i mi or sine-ll pige ol' il smell es shown momie in Figs. 6 and 7 the cradle may be iven e variable relation to the other part', e though the action of' the tension member remains substentiallv the same as has alreed been described. n this adaptation the enc orage end of the compression member is slipped through the wail QOend around the crossbar 2l in e direction opposite from that above described, while the rocker is mede to beer against the concave surface of the Weil 20, the tension screw er'ier passing through the rocker being three-ded through the space between the wall 20 andthe crossber 21 and made to bear in the notch 23. After the free end of t e screw is projected through one of the holes 30 oi the compression member the nut is applied against the outside ci the compression member substantially in the seme manner es before stated, but is drawn by the action of the screw directly toward the inner or convex surface of the well 20 and close 'bo the seme between the Wings 19.

ln the form oi' the inventionshown in the lest set of figures the iension member is in the nature of an 'ey/ebelt Bl'having a threaded poi-tion .Uf and a head llia in place of the heed 16 of the irst form. The eye 32 is in the nature or' e slot perpendicular to the axis of the screw and is .adapted to receive one end of the compression member F295. the end passing inward and foldable under he niein portion of the compression member while the remote end of the compression men'iber applied around the crossbar 2i of the cradle the seme es as in .liigs l and 2. lilith the use of the threaded eyeboli:` 31 it is unnecessary to provide perforutions in the compression member or to weaken the saine by puncturing it. Any piece of strep material either metallic or fabric may be employed with this device and with complete setisfectioln In the applicstion o this form of the inveniion io job the rocker 24C is slipped upon theeyebolt and a Winged nut 33 is vfolien threaded end of the tension member. The hub portion of the Winged nut hears against the Hatter side of the rcckerwhiie the rounded side thereof beers in the bearingn sects 22 the same es, shown in Fig. 2.A Of L the clamp may be employed for use sion'nlA e hose or other devices oi any desired size or diameter. the variation in size .be-4 ing compensated' for by varying; the lengsh of the compression member. One of the useful purposes to which l apply this device is f in the compression of piston rings a at 34 in jdie assembling); of afreciii ing' engine. Grdinarilyf it is e dificul master to insert e piston into n cylinder because' of the expanding action oi t.lie jrihgs.
